Operator Interface Controls
Operator interface controls are located on the front door of the main inverter
enclosure. These controls include an O
N /O FF Switch, 4-line LCD display and
keypad called the Universal Frontpanel Control Unit (UFCU). Additionally there
is an AC and DC Disconnect on the AC Interface Enclosure and the DC Interface
Enclosure Doors.
Main Enclosure Door Interlock Switch
The front door of the PV225S main enclosure is equipped with an interlock switch
to preclude operation while the front door is open. Opening the door of the main
inverter enclosure will initiate an immediate controlled shutdown of the PV225S
and opens both the main AC and DC contactors. The main AC and DC contactors
cannot be closed unless the door’s interlock is in the engaged position. The
PV225S is prevented from being restarted until the door is again closed and the
switch is in the engaged position.
It is required that the PV225S main enclosure door must be locked during normal
operation. The door interlock switch does NOT remove all hazardous voltages
from inside the inverter. Before attempting to service the PV225S, follow the
de-energize Lockout and Tag procedure on
page x .
